Thanks for the suggestion.
In reality, I plan to set up the gui prompt for when I use my pgp keys with other applications like Git or VSCodium and not to sign messages or documents.
From what I researched, I just need to put pinentry-program /usr/bin/pinentry-gnome3 on gpg-agent.conf and pinentry-mode loopback on gpg.conf and it should work fine.
I migrated from Debian 10 to Fedora 33 and I don’t know if it’s due to the packages being newer or some fedora settings but the gui prompt doesn’t work by default.
